There aren't really any N2 volume temperature sensors near the electronic panel so I would not use those as an indication of temperature in the EP.<br>

If you're fine with running RICH with no hardware interlock temperature sensors in the electronic panel and relying on the software interlocks using FGPA temperature readout, then it can wait.</div>

I may be able to remotely override the EP cRIO so RICH can be turned back on. If that doesn't work, someone will have to go turn a switch on the chassis in the hall.<br>
